There have been more leaks about the innovations we may see with the iPhone 5S and the iPhone 6.

While there may be no major shake-up in terms of design for the iPhone 5S, users may see a significantly improved display. The phone could also come with a 12 megapixel camera and dual LED flash.

There may also be some form of fingerprint scanner, an idea which has been doing the rounds since a developer found plans for biometric scanning in a folder tucked away in the iOS7 beta.

Looking ahead to the iPhone 6, patent filings have suggested this smartphone might be the first in the world to have a liquid metal handset, and could be launched along with a plastic-bodied budget iPhone as early as this autumn.

But a statement by Apple CEO Tim Cook would seem to suggest there will be no larger screen in the new version of the phone.
